Hello Thank you for your help. It looks like I might have a chance to get ldp working in a small network using your implementation... I'd like to try out some things tomorrow with the old version of quagga (I have the suspicion that I issued some conflicting commands), but I think I'll switch to your development version soon, and help you track down and maybe fix some bugs. When I switch to the development version, it's possible that I'll ask some questions on how to install it. But I'll ask then. Now, I'd like to ask a few questions, about the current ldpd: 1) can it be controlled by vtysh, or is it only controllable by telnetting to its port? (I noticed that some options weren't available when telnetting (for example mpls-te commands)) 2) Should LDP be activated only on the desired interfaces (with the interface eth0; mpls ip; commands) or globally (with mpls ldp)? I tried setting both of them (and one of the machines froze). Does it matter in which order I configure them? (I configured the interfaces first, then the global operation mode - and only then it started sending out LDP Hello packets) - I will try both ways with the current LDP. 3) Is labelspace 0 set by default as a 'per platform' labelspace? If I want to use per interface labelspaces do I have to set the number to something else different from 0? And is this true for static labels as well as LDP? Thank you kindly and I look forward to help you as best I can On 3/13/06, James R. Leu <jl...@mi...> wrote: > It is mostly implemented, which just bugs to fix. I'm sure there are > plenty of though.
